Abstract: Abstract Heterocyclic amines were diazotized and coupled with 8-anilinonaphthalene-1-sulfonic acid magnesium salt to synthesize some new heterocyclic monoazo dyes, showing ammonium-azonium tautomerism. The structures of the dyes were characterized by 1H‐NMR, MALDI, FTIR, and UV–Visible… read more here.
